> Currently, Falcon retries only on failure. We should extend support in case
> of timed-out instances too. Earlier, since we were relying on post-processing
> to notify the instance status, this was not possible. Now that Falcon relies
> on Oozie JMS notifications, we can support retries for timed out instances
> too.
> If a dataset is expected to get delayed for a long time, the user is
> currently forced to supply a large timeout value. This is an overhead in
> terms of Oozie having to poll for that long. If we introduce retries, the
> timeout can be a reasonable value with periodic/exponential back-off retries.
